WebRTC Mobile Voice Call Platform

I’m building a startup MVP that lets two users talk instantly over voice on their Android or iPhone. The call is one-to-one, established through WebRTC, and the match is made automatically by the system according to the “mood” each user selects—no contact list, search box, or invite link involved...
